The best time of the day to scrape is usually around 9-10 am, as the morning is the time when the body’s qi and blood are born, and this time the scraping is good for the qi and blood to flow smoothly. It is a traditional Chinese medicine treatment that can move qi and blood, unblock metabolism, improve meridian blockage, and relieve muscle aches and weaknesses. Patients are advised to perform Gua Sha treatment between 9-10am for best results. And in the afternoon or evening, when the qi and blood gradually enter a closed state, the effect of gua sha will be greatly reduced. In addition, because scraping increases the body’s metabolism, it is best for patients to do it after eating, but not too full, and also to ensure that the room temperature is appropriate to avoid catching a cold. In addition, you should not take a shower immediately after scraping, it is recommended to wait for about 6 hours for the skin pores to close before taking a shower.
